Application filed November 24, 1882. (No model.) lz1(euted in BelgiumMay 13, 1583, No. 517,900, 111111 in Italy June 30, 1889, XVI, 14,290fmfl XXVIII, 401

To all whom zt may concmn:

Be in known thai; I, SIEGFRIED MARCUS, a subject of the Emperor nfAustria, residiug at the city of Vienna, in che Austro-Hungarian Empire,have inventecl certan new and useful Improvemeuts in Magneto ElectricGenerators; and I do hereby declama the f'ollmving to be a full, clear,ami exacb descrption 01" the invention, such as Will euab1e othersskilled in the art to which t appertains to make and use the same,reference beng had to the accompanying drawings, and to letters 01figu1es 0f reference marked thereon, which form apari; of thisspecification.

This inveution has for its object to provide a, means f01 automaticallyiguiting gases or lquids by an electric spar; produced from a currentgenerated by a magneto-electric generatox, thereby dispensing With theusual batteries and Ruhmkorff apparatus, and which is effective in a dryas Well as a danup atmosphere.

My new iguting apparatus referred O in un applicatiou for patenti forimprovements in gas-engines filed June 12, 1882, consists of amagneto-electric generator and the proper lighter. The sad generator maybe a continuously-rotatng magneto-electrc apparatus, 01 may consist ofmagnebic inductors acted by periodcal mechanical impulses.

In the accompanying drawings is shown an igniting apparabus With agenerator of the first descript-ion. Figures I, 2, and 3shownelevafoion, in vertical longtudina] secton, and byau end view thsmagneto-electric generator; nnd Fig. 4 shows its application to agas-engne '01 igniting and exploding the gases.

Like letters ot' reference indcatelike. purts wherever snch may occnr inthe above figures 0f drawings.

L aml L are two metnllc (i1ou) segments thai. form che two poles of apowerful fleld magneti or magnets, M, Whch lntter is c0m posed of aseries of bar-nmgnets, m m m, &c., and the metallic framing M, l'0 whchsnid bar magnets are screwed. The polc-segmcnts L L are attached to asquare plate, M 01" amaterial not influenced by magnetsm, aud Whichserves as a support aud cover for the same. As shown by Fig. 3, thebar-maguetsmare a1 ranged radially upon the pole-segmeuts and. in twogroups of an equal number opposte each other. TLese two g1ou psofbar-magnets may, however, be replaced by two single powerful mugnetsofz1 snitable form.

Between the pole-segments is located theinduction-col O und its armatureO, mouuted upon a two-parhsmft, S S. The armaureis composed of ametallic core, 0, and two metallic disks, 0", (of smt i1'011 01 othersuitable metal.) Thecoil 0 i. composed of a bobbin, o, 01" a suitnbleisolating substance, mounted on the core 0, and npon Which is wound t'neisolated copper WI'G 0 one end of Which coi! is connected With themetallic part of the apparutus, md the other With EL sleeve, 0 mountedupon the part S" 0fthe two-partshaft, and from which in is isolated. Thelatte1 part of' this shaf; has its bearings in the framng M and a plate,Q, and (116 pari: S of said shal't bus its bearings in a plute, Q, andthe plate M said plaes Q Q being secured to the armature O un serve toconnect the shai't therewith. Tl1e plate M cflnies a bindingscrew, msoluted therefrom, sair1 screw being in metalc connection wth tne sleeve0 through tlm meullc bar on and he contnct spring s. Upon the pmt Softhe shn't Within che framing 01' supporting plato M is mounted aslotted lever, L which is nctnnted or carried a'loug by the piu 01. stm1l' sccured to a belt-pulley, p mounted upon u short; shaft, S hut busits bearings in the metullic framing M, saifit shaft hming its bemingseccentric to those 01' shaf't S 8, and beng rotated in any way by meansofits belt-pulleyfif01 instance, through a belt-puley on the manornuk-shai'n of the gus-engine t0 Whch the ignitng appmatus belongs. ymeu.ns 01 his: arraugement a differential spced is impzuted 110 theshafi; S" 8 and iuduction-col.

As the ignting and exploding of the gas 01 liquid mnst in 1111 cnses becf'ected ab 1egulnl ntervals, zmd ns the regularity 0f tu: intervalsdepends on he uniform rotaton of the shaft S S", upou whch is mountedthe cmn T, hereinafter described ,and operuting the lghtel, .hennformity 01' the 1om3 movementof puley and of thatpuley 01' the cugineWhich actnates in by mem1sof IL hall. m card is 01' grent importance.This end ma; be 0hmined in any desred mmmer aud by any 01'' theWellknown menns, hme, ns shmvn in Fig. 4,

constructed the two belt-pulleys with periphe1al recesses k and thebeltB with projections or teeuh IP, that engage the recesses 76, andthus uniformly rotate the pulleys, end prevent any slip of the belt B.

By the above-described constructon and extension of the poles of thefield magnetzor magnets over the entile width of the1m1e-segmente on theone band, end especally the application of the levcr movemen to rotatetheimluction-col on the other band, the armature is exposed suficientlylong to the magnetic influence of the bar-nmgnets to secure a completeand shoxough magnetzation thereof, while the clmnge in polarty followsvery rapiclly.

Having describc1l the magneto-electric generator, I Will now deseribethe lighter itself'.

Upon a standard, F, secure l to the plate M ofthenmgneto-electricgenerator,s secmed an angular or two-armed lever, U, andopen he part S of the two-part shai'b of suid generator is mounted acum, T, npon which rdes the extremity ()f tlxe urm u of levor U, whicl1extremity me be provided Wth un antifrction rolle1, u, t'or obviouspurposes. The axm u" of lcvcr U carries a metallc pio, U, thai:penetrates into the cxploding-chamber a. The pin moves gas-tght wibhnthe aperture through whieh it passes and carrics a coiled spring, n",the tension of which tends to force the lever-arm zunl pin outwmwl fromthe explocling=chamber o. A second pin, U projects some dsmnce into theexploding-chamber and upon the same plzme as the pu U, the poles of theinductiomcol beng connected with said pins by wres w 10 through thebifiding-screw m and the metallc portion of the generator. As planlyshown in Fig. 4:, euoh pio U U terminates in an enlargement on contactpoint or button M M, respectively. As the cam T rotates, the arm u oflever U s slowly moved inward, when the roller u moves up the incline ofthe cam, and when al; ts highest point or greatest dstance from thecenter of the cam tho contact-point M et pn U Wll be in contact wtl1 thepoint u of'pn U, and immediately thereafter the extremity of thelever-arm u will drop over che nose t of the can1 T end the contact ofthe two plus Will be interruptecl. Thc sudden uterruption of thecontacfi between the points u1fiproduces the spar; that igntes the gas01 liqud in chamberc. Thus it will be seen thai; ab each revouton of thecam T the gas 01 liquid is gnited.

1 have clescrbed hereinbefore mechnnism whcreby a differential motion isimpa1ted to the inducton-coil and its shaft, and the object; ofimpartingsuch a movement to the 0011 and shaft Will be appar'ent, for the reasonthai; it is necessary that the coil, during il portico of its rotatonshoulcl. be moved. suflciently slow to insure its thoroughmagnetization, in order to obta'm the necesszwy current strength 1:0produce tho spark, and it slxould oc moved sufioently fast to break thecurreut as suddenly as gossible, in order to produce the spark to ignitethe gas 01 lqud; and, as will be readily understood, the cmn T Wll be somounted upon,its shaft; as to cause the separaton of the contact-pns abche proper time; hence sa l cam is operated from and timed by therotato1y movement of a pulley mounted upon some suiteble part of theengine With whch the igniting; apparatus is combined. Moreover, thealternate closng end breaking of the contact between pins U md U musi;correspond in such a manner to the movement 01' che imluctioncol whchproduces the current; that Sll pns are in contact durng themagnetization of the core, and separate uhcmselves suddenly in themomentwl1en denmgnetizution begins-fiz,, Whon thov polmfy of the core isreversed.
